Which row of the table shows two correct equations that can be used to calculate the current I I\,I through a filament lamp?

Equation 1Equation 2
AI=V÷RI = V \div RI=V÷RI=P÷VI = P \div VI=P÷V
BI=R÷VI = R \div VI=R÷VI=V÷PI = V \div PI=V÷P
CI=V÷RI = V \div RI=V÷RI=P×VI = P \times VI=P×V
DI=V×RI = V \times RI=V×RI=P÷VI = P \div VI=P÷V
